How convert/replace all Images to WebP in all my posts

Hello all, I tried Converter for Media plugin, and it ruined my website (changed all image URLs with mask to their .php image view ).
that’s not what I wanted, and it’s really bad for SEO (long story).
I could use shell script to convert all images on server to WebP but in that case I still need to replace all attachment URLs in the DB for all my posts, and this will take from me more effort + it won’t be guaranteeing (e.g I could break my website if I set wrong SQL query to replace them),
is there a better method or an Plugin that works.
